We're dividing 90939640 by 980 
The aim is to understand the frequency of 980 in 90939640.

Moving on to step 1:
980 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 980

Let's proceed to step 2:
980 goes into 90 0 times with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Bring next digit (9) of the dividend behind the 90 and repeat the process: 909 / 980

Advancing to step 3:
If we divide 909 by 980, we get 0 and a remainder of 909.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 909 after subtracting 0 from 909.
Bring next digit (3) of the dividend behind the 909 and repeat the process: 9093 / 980

On to step 4:
980 can be fit into 9093 9 times, resulting in a remainder of 273.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 8820 from 9093 to get 273.
Include the next digit (9) from the dividend after 273, then repeat: 2739 / 980

On to step 5:
2739 divided by 980 is 2 with a remainder of 779.
The next digit of our result is 2. 
Result so far: 92.0
Subtracting 1960 from 2739 leaves us with 779.
Take the next digit (6) from the dividend and append it to 779, then repeat: 7796 / 980

Step 6:
If we divide 7796 by 980, we get 7 and a remainder of 936.
Record the quotient 7 as the next digit in the result. 
Result so far: 927.0
Subtract 6860 from 7796 to get 936.
Take the next digit (4) from the dividend and append it to 936, then repeat: 9364 / 980

Step 7:
980 goes into 9364 9 times with a remainder of 544.
Record the quotient 9 as the next digit in the result. 
Result so far: 9279.0
Subtract 8820 from 9364 to get 544.
Include the next digit (0) from the dividend after 544, then repeat: 5440 / 980

Let's proceed to step 8:
5440 divided by 980 is 5 with a remainder of 540.
The next digit of our result is 5. 
Result so far: 92795.0
The remainder is 540 after subtracting 4900 from 5440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Step 9:
The number 980 fits into 5400 5 times, leaving a remainder of 500.
The next digit of our result is 5. 
Result so far: 92795.5
The remainder is 500 after subtracting 4900 from 5400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 10:
980 goes into 5000 5 times with a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 92795.55
If we take 4900 away from 5000, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 92795.55 with a remaining 0.1.
